STATEN ISLAND, N.Y. -- FDNY, NYPD and Department of Environmental Protection officials are on the scene outside Borough Hall, where an apparent water-main break is causing a flood of water to cascade onto Bay Street.

According to a witness at the scene, a portion of the sidewalk and street at Nick LaPorte Place appears to be buckling amid the brown water, and "a river" is gushing onto Bay Street, outside the St. George Ferry Terminal.

Officials are attempting to locate the main to shut off the water, according to emergency radio transmissions.
